STEAM, WATER, AND FLUID VALVE.

SPECIFICATION forming part of Letters Patent No. 452,312, dated May 12,1891.

Serial No. 362,443. (No model.)

To all whom it may concern.-

Be it known that I, FOSTER M. METCALF, a citizen of the United States,residing at Battle Oreek,in the county of Calhoun and State of Michigan,have invented certain new and useful Improvements in Steam, ater, andFluid Valves, of which the following is a specification. I

This invention relates to an improvement in steam and other valves; andit consists in providing a cheap, simple, effective, and durable valvewhereby the practical difiiculties' caused by wear, leaking, andsticking, due to dirt, grit, and unequal expansion of the parts underhigh temperatures, &c., are entirely obviated and overcome. For thispurpose I employ a valve of such simple disk-form construction that asingle current of steam, water, or other fluids or liquids maybe dividedand its parts distributed, one, two, or more circuits united and theirconstituents commingled, directed, controlled, and delivered, and,further, as preferably constructed, without stuffing-boxes or othervexatious hinderances to the free and easy manipulation and durabilitythereof. As preferably made, my novel valve has no stein-opening to theatmosphere from the receiving-chamber against the incoming current, andthe flat rotary seatsurface thereof renders the use and wear aself-preservative of a tight joint, at all times, and its constructionand use are such that it ofiers no place for lodgment of dirt or gritthereunder, as a mere inspection of the drawings will show.

In the accompanying drawings is shown the manner in which I apply mynovel invention to a steam-pump for combining the exhauststeam with thewater being pumped.

Figure I represents a rear view of the valvecasing with the disk valveproper removed. Fig. 11 is a vertical section of the same, drawn on thedotted line of Fig. I. Fig. III is a face view of the disk valve proper,and Fig. IV is a representation of the same turned at a right angle.Fig. V is a partial inner view of the side of pump to which the casingis to be attached, showing the suction and exhaustchambers thereof, Tand B, respectively.

The same letters and numerals of reference are used to designate thesame or corresponding parts in the several figures.

A is the disk valve, which is received by an annular chamber 0, formedin the valve-casing B, and is seated against the inner wall 1 of saidchamber. This casing B is formed with passages i 2", which respectivelycommunicate with the valve-chamber 0 above and below the center thereofthrough passages b and a. The passaget' opens into the atmosphere andthe passage t" leads to the suctionchamber T of the pump through chamberK, passage 6, and ports D D, said chamber, pas sage, and ports being allformed in said casing. \Vithin the passage K is located a check-valve J,which is seated on the flange 2, and is designed to be automaticallymoved away from its seat to open said passageby The casing B is securedto the side of the pump by bolts or other suitable fastening means,which pass through the holes 15, said holes and the port D facing andregistering with corresponding holes 75 and the port D, and is solocated with respect to the pump that its valve-chamber C will face theexhaustchamber R thereof.

The disk valve A is provided with a shaft or stem .9, which has itsbearing in the valve-seat and extends therethrough to the outside ofsaid casing, being provided at the latter point with anoperatinghand-leverZ,which is formed at its lower end with an innerannular recess or chamber 0 for the reception of a spring a, which iswound loosely around the valve-shaft s at this point, and also with anotch 01, which in conjunction with a stop g, secured to or formedintegral with the outer side of the casing B, adjacent to the hub hthereof, limits the throw of said lever. The valve is formed withopenings at and Z), which respectively are intended to register with thepassages a and b in the operation of the device.

The mode of operation of my improvement 10c as applied to the steam-pumpfor combining the exhaust of the engine with the water being pumped isas follows, to wit: With the operative lever in a vertical position,Fig. III, steam is admitted through port I) of the disk valve A anddelivered by ports I) and 'i i of the casin g to the atmosphere. Now bythrowing the lever to a horizontal position, as indicated by the arrowand dotted lines, steam is deflected and directed through port a of saidplate B, now registering with a of the disk valve, whereby the currentthereof, actuating the check-valve J, passes through chamber k,

passage c, and by ports D D to the suctionehamber T of the pump, whereit is instantly condensed by the water there present and carried onwardto the steam-boiler or other desired destination. I have here preferablyplaced the spring 0 upon the chamber-stem a of the disk valve in lieu ofon the lever end of the valve-shaft 5, although the said spring is not anecessity in either form shown. The lever Z may be returned to itsclosed or normal position, or vice versa, by means of a spring placedopposite the lever-stop g, and the cap m closes the inlet-chamber, asseen.

For the purpose of adapting my invention to drinking-fountains,water-coolers, and the like, a spring placed suitably opposite the stopg, Fig. II, may be used, as is evident.

Having thus fully described and illustrated my invention and pointed outsome of the uses to which it is adapted, what I claim, and desire tosecure by Letters Patent of the United States, is

1. In combination, a steam-pump, the attached casing provided withsuitable ports, passages, and chambers, a check-valve within the sameand connected with said ports and passages, the disk valve coactingtherewith, having one or more ports, and a circular shaft having itsbearing extended through the diskvalve seat to the outside of saidcasing and the operative lever thereto attached, substantially as andfor the purposes illustrated and described.

2. In combination, a steam-pump, a casing fixed thereto, having suitableports, passages, and chambers, a check-valve connected therewith, and adisk valve provided with one or more ports therethrough and having acircular shaft or stem extending through the said diskvalve seat to theoutside of said casing and there provided with the operative lever.

23. In combination, a steam-pump, the attached casing provided withsuitable ports, passages, and chambers, a check-valve therein andcoacting with said ports and passages, the disk valve having ports a Z),valve-seat, and ports a b, passages i t', chamber 7t, passage (2, portsD D, disk-valve shaft .9, carrying spring and operative lever, allconstructed, arranged, and operatingsubstantially as shown, and for thepurpose set forth.

4. In a steam-pump, the attached casing provided with ports,passages,and chambers, the cheek-valve J, chamber 70' in connection withsaid ports and passages, the cap I, provided with recess or here forstem 70 of said check-valve, the disk valve provided with ports orpassages therethrough and in connection with the ports and passages ofthe casing and having a shaft projecting through the seat thereof to theoutside of said casing, and the operative lever fixed thereto,substantially as shown and described.

In testimony that I claim the foregoing I have hereunto al-Tixed my handand signatn re, this 19th day of July, A. D. 1890, in presence of twowitnesses.
